Commencement of Exploration Programme at Duékoué, Côte d’Ivoire

Highlights

• Team mobilised, land access granted and work programme has commenced
• The programme comprises ground magnetics, geological mapping and soil sampling along approximately 137.52 line-kilometres of traverse lines
• Approximately 2,780 QA/QC-validated soil samples are planned for analysis by ALS, with the fully funded programme expected to be completed within approximately three months

Serval Resources Plc (AIM: SRVL), a company focused on building an independent copper and future metals developer, is pleased to announce that field exploration has commenced at its Duékoué copper-gold-molybdenum (“Cu-Au-Mo”) project in Côte d’Ivoire.

This work programme is as announced on 19 June 2026 and follows completion of a stakeholder and local community engagement programme across the project area, undertaken ahead of mobilisation. The engagement programme included meetings with local administrative and traditional authorities in Duékoué, including the Prefect, Sub-Prefect, Gendarmerie Commander, Chief of Police and a representative of the Ministry of Mines, together with representatives of all seven villages within the project’s area of influence.

CEO, Robin Birchall, commented:

“It’s exciting to now have field work underway at all three of our projects in Namibia, Botswana and Côte d’Ivoire. Duékoué is a particularly interesting project given how underexplored this part of Côte d’Ivoire remains for copper, gold and molybdenum.

“Côte d’Ivoire is already home to some of West Africa’s best-known gold mines, all sitting within the same ancient geological terrain that extends across much of the country, including our licence area at Duékoué. This is some of the oldest and most mineral-rich rock in the world, and it is exactly this type of geology that has produced world-class discoveries elsewhere in West Africa over the past two decades. We believe the same underlying potential exists for copper, gold and molybdenum at Duékoué, which is what makes this such a compelling place to be exploring.”

Côte d’Ivoire – Duékoué Project

Duékoué is a 399 km² licence (PR0911) held under a joint venture and earn-in agreement with La Minière de L’Eléphant SARL (“Laminele”), strategically located on the Archean-Proterozoic boundary in Côte d’Ivoire. The project hosts a Cu-Mo anomaly first identified by state mining company SODEMI in the 1970s and verified by Serval during its 2025 work programme. Multiple soil samples taken by Serval have also established moderately anomalous concentrations of gold which warrant further evaluation of the project as a potential Cu-Au-Mo project in due course.

The programme has been designed in two phases:

The expected outcome for this work includes:

• a combined geochemical, geological and geophysical dataset generated by this programme; and
• definition of a soil anomaly together with favourable underlying structural features and/or lithological contacts, that will be used to refine and prioritise follow up exploration targets.
